COMB.[NATION GAS AND on. BURNER.

Specification of LettfiI-Q'atent.

. Patented Nov. 29, 191%.

Application filed December 11, mos. Serial No. 532,587 w To all whom it may concern:

a citizen of the United States, residing at Indianapolis, in the county of'Marion and Stateot' Indiana, have invented certain new and useful Improvements in Combination Gas and Oil Burners, of which the following is a'sp'ecification. j

This invention relates to improvements 1n burners for burning gas as fuel in stoves- .and furnaces, and while the invent on is not limited in its application, it is primarily intended for domestic use.

The object of theinvention is to superheat the gas previous to ignition, and to provide means for the thorough admixture of air with it to insure perfect combustion and a blue flame.

Another object of my invention is to utilize crude or more or less refined oil for the generation of the hydrocarbon vapors .or gas to be supplied in whole or in part to the gas burner. I

I accomplish thefobjepts of my invention by the mechanism illustrated in the accompanying drawings, in which- Figure l is a top plan view of a circular embodiment of my invention such as is adapted for use in cylindrical stoves or furnaces. Fig. 2 is a detail view showin the lower part of a stove with my improve burner installed therein, the view showing the several parts in vertical section on the line 2-2 of Fig. 1. Fig. 3 is a View in vertical section of the burner and heating dome, removed from the other parts of the device, the section being on the line 33 of Fig. 1. Fig. 4 is a horizontal. section on the line 4.. .4 .of Fig. 2. Fig. 5 is a detail view in vertical section'of a stove or furnace having a rectangular fire-pot, and showing a correspondingly modified form of my device, and Fig.6 is a detail view in horizontal section on the line 66 of Fig. 5.

Like characters of reference indicate like parts throughout the several views of the drawings.

7 represents the side walls of a stove or furnace and 8 the bottom thereof.

9 is the horizontal base-plate of the main or body portion of my improved burner, upon or from whichthe other'parts are supported, The p'late'9 is supported by t walls 7 of the stoveor to t inclusive of the drawings, I have illustrated that form of my device which is inv tended for use in Be it known that I, GREENE ALL N SMITH,

furnace. In Figs. 1'

connection'with a cylindrical stove, and, consequently, the plate 9 is circular'inshape. It is provid'd with a round central; opening .which is surrounded by an upwardly projecting and inwardly sloping flange 10, A series of-vertical and radialflanges 11 are formed integral with plate 9 and flange 10 for the purpose of strengthening the parts thus connected andmore particularly for the purpose of preventing the warping of parts 9 and 10 when heated to a hightemperature. Supported by the radial flanges 11 is an annular vertical flange 12 of greater diameter than the flange 10, and -integral with the'vertical annular flange 12 is an annular horizontal plate 14 which extends inwardly of the annular flange 12 from the top portion of the latter. Connecting the parts 12 and 14 and integral with them are the radial and vertical flanges 16 which register with the flanges 11 so as to form continuations of the latter. Displacement of-the is prevented by notching the flange 10 to receive the flanges16, and by reducing the heightof flanges 11 to a'level with thebottoms of said notches to receive flanges 16 and.

also to form shoulders 17 in the radial flanges 11 th retain the position of the annular-flange 1'2.

The plate 14 has a central opening which is surrounded by 'an upwardly projecting rib or flange 18. Resting upon the flange 18 is a concave late or dome 19 which has a marginal vertical flange 20 which surrounds placement of said dome 19. Extending from one side to the other of the concave plate 19 and. preferably with a higher arch for its outer wall, as shown in Fig. 8, and a lower arch for its inner wall, is a superheating chamber 21, which'communicatcs at each of its ends with vertical passages 22, and these assages 22 discharge into an annular chamer 23 which is surrounded by the flange 10 and is sufficiently remotetherefrom' to'allow for a free circulation of air between the walls of the chamber 23 and said flange 10. The outer walls of the annular chamber 23 parts 12 and 16' the rib or flange l8 and prevents lateral dislos are provided with a series of perforations 24 through which the superheated gas will be discharged. Opposite each'of the perforations 24. is a perforation 25 through the flange, 10. The as issuing from the chamber 23 to the ho es 2 1' will ass on through the holes 25 and'will be ignited on the outside of the flange 10. Air will ing a packing of mixture with the gas from pipe 27, in the through pipe 32, perhaps without being vainto two compartments which communicate be admitted 1 from both top and bottom'around the walls 5 of the chamber. 23, and as the gas passes 1 across the open space between the flange 10 l and the perforated wall of chamber 2 3 the l air coming in above and below will mix with the gas in sufiicient quantities to produce a thorough combustion of the hydrocarbon, vapors. Should the heat not be sufficiently intense, it can be increased by shutting oil the air from above the chamber 23 by placasbestos between the upper walls of chamber 23 and flange 10.

26 is a gas supply pipe which discharges into the superheating chamber 21.- A leading-in pipe 27 from any suitable gasometc-r or source of supply discharges into the lower end of the pipe 26,'and this lower end of pipe 26 is preterably expanded asshown in Fig. 2 for the admission of air and its adpipe 26 before its discharge into-the chamber 21. I V

Located at one side of the chamber 21' is .a wall 30 which connects the top of chamber 21 with the lower edge of dome l9 and forming a closed chamber above said dome 19. A pipe 31 supplies oil under pressure to the last named chamber, and a pipe 32 conveys the vaporized oil from this chamber and discharges it into the bottom of thepipe 26. The oil-chamber is provided with a vertical partition 33- at its major upper portion whereby the oil-chamber is divided with each other below the partition 33 thereby compelling the oil entering on one side through pipe 31 to pass down under the partition 33 and become yaporized by the intense heat of the'wallssurrounding this oilchamber and to enter the discharge pipe 32 in vapor form. Without the partition 33 the oil would pass directly r across and out porized.

It will be noted that the principal parts of my device are readily separable. Thus the plate 9 with its flanges 10 and 11 only loosely support that portion comprising the member 12, 14 and 1G, and the dome-plate 19 with its integral and attached parts are loosely supported upon the plate 1%. This enables the device to be quickly dismantled l for shipment or for renewals and repairs or other purposes, and to facilitate this separal tion, and for greater convenience and cheap l ness in the process of manufacture, I prefer to divide the plate 9 and ilMlPfi 10 on the lines and the flange 12 ancf plate 14 on i the lines 36- In the modification shown in Figs. 5 and 6 the super-heating chamber a1 is separated from the chamber 42 from which the gas 1 issues through the holes 4:3, by n eans of a vertical partition 4:4: having passageways at its ends. This partition compels the gas entering through pipe 26 to pass around the partition as so as to give itthe maximum heat exposure. Holes .43 may be formed through the top horizontal wall of chamber 42 as well as through its outer vertical wall and thus the capacity of the burner may be practically doubled. The vertical flange 10 has the opening 25. here shown as a continuous slot, for the same purpose as previously described, and a like opening will be formed in the horizontal plate above the burner. Air for mixing purposes will be supplied from two directions, that is, from below, and also from the opposite direction by coming around the back of the chamber il as shown by the arrows in Fig. 5. The oil chamber in this modification is shown at 50 and is piped in the same manner as for the other form of the device, already described.

Having thus fully described my invention, what I claim as new and wish to secure by Letters Patent of the United States, is
